those are the ones. I got one many years ago, but either sold it or it is lost. I bought a couple of sheets from Freestone. Had not looked at other sheets. For printed sheets it might be worth consideing getting the done on transparent plastic, like the old PC kits. Not sure of cost, otherwise get them printed on A4 sized label pabel, which can then be fitted to transparent plastic. To do complete coach side best to start with original drawings, as my drawings only show outline. I know some like their models in museum(non running)condition, but I prefer them in real condition, and given the air polution, paintwork would not have been that clean in service. The 3D printed plastic can be smoothed down quite a bit, it is not as bad as some suggest, and it is better than it used to be. Some form of transfer sheet for the sections of lining mght work One reason I started in 3D was that models are only produced to order, so no need to invest in stock up front. If range is too big, stocking up becomes a nightmare. If there is an easy to use online service use it.I have looked into that option for laser cutting and it can be expensive. Silhouette cutting is more a craft activity and I have not found anyone offereing aservice. I think if anyone was up to it, it might be a good business venture, but until there is such a service I am sticking with 3D printing.
